#    1. Make this script executable:  "chmod +x macosx-xlf.sh"  #
#    2. Build as root:  "sudo ./macosx-xlf.sh"                  #
#    3. Tested on:  Mac OS X Panther 10.3.6,                    #
#       IBM xlf Fortran compilers,                              #
#       GCC version 3.3 C/C++ compilers                         #
